3 Product description • Electronics versions Modification status, electronics as of -01 The instrument is available in different electronics versions. Each version can be identified via the product code on the type label: • Standard electronics type PT30E-XX Scope of delivery The scope of delivery encompasses: Application area The instrument is suitable for applications in liquids and bulk solids in vessels under difficult process conditions.
3 Product description Transport inspection The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with. Storage Up to the time of installation, the packages must be left closed and stored according to the orientation and storage markings on the outside.
3 Product description The handling of radioactive substances is regulated by law. The radiation protection rules of the country in which the system is operated apply first and foremost. In Germany, for example, the current radiation protection ordinance (StrlSchV) based on the Atomic Energy Law (AtG) applies. The following points are important for measurement with radiationbased methods: Handling permit A handling permit is required for operation of a system using gamma rays.
3 Product description for control areas in the guideline of the respective authority (in Germany, for example, the radiation protection ordinance). 41779-EN-131119 We are at your disposal for further information concerning radiation protection and regulations in other countries.
4 Mounting 4 Switch off source Mounting 4.1 General instructions The source container is part of the measuring system. In case the source container is already equipped with an active isotope, the source container must be locked before mounting. Danger: Before mounting; make sure that the source is securely closed. Use a padlock to secure the source container in the closed condition and prevent it from being inadvertently opened.
4 Mounting Installation position 4.2 Mounting instructions Note: Along with the planning, our specialists will analyse the conditions of the measurement loop to dimension the radiation source (isotope) accordingly. You get a "Source Sizing" document specifying the required source activity and containing all relevant mounting information for your measuring point. You must follow the instructions of this "Source Sizing" document in addition to the following mounting instructions.
4 Mounting and protective grating so that no one can reach into the dangerous area. Sensor orientation Level detection - max. detection The POINTRAC 31 is suitable for level detection in liquids or bulk solids. It is mounted at the height of the requested switching point. Fig. 4: POINTRAC 31 as max. level detection (uncovered) Level detection - min. detection 14 POINTRAC 31 • Foundation Fieldbus 41779-EN-131119 Fig. 5: POINTRAC 31 as min.
4 Mounting Bulk solids with low density Fig. 6: POINTRAC 31 as level detection (top view) POINTRAC 31 lends itself well for level detection of bulk solids with low density. Mount the instrument horizontally at the height of the requested switching point. Mount the source container VEGASOURCE displaced by 90° in order to get the widest possible radiation angle. When the sensor is covered by the medium, the radiation damping is considerably stronger - hence, the switching point is all the more reliable.
5 Connecting to power supply 5 Safety instructions Connecting to power supply 5.1 Preparing the connection Always keep in mind the following safety instructions: • • Connect only in the complete absence of line voltage If overvoltage surges are expected, overvoltage arresters should be installed Voltage supply Power supply and digital bus cable via separate two-wire connection cables. Power is supplied via the H1 voltage supply.
5 Connecting to power supply T-distributor, the screen of the short stub to the sensor must not be connected to ground potential or to another cable screen. The cable screens to the power supply unit and to the next distributor must be connected to each other and also connected to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). Low-frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains.
5 Connecting to power supply 6. Insert the wire ends into the round openings of the terminals according to the wiring plan Information: Solid cores as well as flexible cores with cable end sleeves are inserted directly into the terminal openings. In case of flexible cores without end sleeves, press the rectangular lock opening with a small screwdriver; the terminal opening is freed. When the screwdriver is released, the terminal opening closes again. 7.

6 Set up with the display and adjustment module 6 Mount/Dismount display and adjustment module 6.1 Set up with the display and adjustment module Insert display and adjustment module The display and adjustment module can be inserted into the sensor and removed again at any time. It is not necessary to interrupt the power supply. Proceed as follows: 1. Unscrew the small housing cover 2.
6 Set up with the display and adjustment module 6.2 Adjustment system 1 2 Fig.
6 Set up with the display and adjustment module Main menu The main menu is divided into five sections with the following functions: Setup: Settings, e.g.
6 Set up with the display and adjustment module Enter the requested parameters via the appropriate keys, save your settings with [OK] and jump to the next menu item with the [ESC] and the [->] key. Setup - Application Enter here, the respective application. Setup - Background radiation The natural radiation on earth influences the accuracy of the measurement. This menu item enables adaptation of the sensor to the requested application.
6 Set up with the display and adjustment module Setup - Adjustment uncovered (single point adjustment) This menu item appears only if you have selected "Single point adjustment" as adjustment mode (Setup/Adjustment mode). In this menu item you determine the point at which the POINTRAC 31 should switch in uncovered status. Empty the vessel until the sensor is uncovered. For this enter the requested pulse rate manually or let the rate be determined by POINTRAC 31.
6 Set up with the display and adjustment module Adjustment "covered" (two-point adjustment) This menu item appears only if you have selected under adjustment mode (setup/adjustment mode) the "Two-point adjustment". In this menu item you can set the min. pulse rate (ct/s) at which the sensor should switch over. Fill the vessel until the POINTRAC 31 is covered. You thus get the min. pulse rate (ct/s) for the "covered" adjustment.
6 Set up with the display and adjustment module You can let the adjustment point be determined by POINTRAC 31. Setup - Relay In this menu item you can select which mode the sensor should operate in. You can choose between overfill and dry run protection. The relay outputs of the sensor react accordingly. Overfill protection = the relay will deenergise (safe condition) when the max. level is reached. Dry run protection = the relay will deenergise (safe condition) when the min. level is reached.
6 Set up with the display and adjustment module This parameter is described in the operating instructions manual "Display and adjustment module". Diagnosis - Adjustment data Here, you can retrieve the adjustment value of the sensor. This is the percentage value of the max. pulse rate at which the sensor switches over. If you have carried out a single point adjustment, this is the entered value. With a two-point adjustment, this is the calculated value.
6 Set up with the display and adjustment module Information: 10 minutes after the key was pressed for the last time, the simulation is interrupted automatically. You can also interrupt the simulation with the switch on the electronics module. Diagnosis - Calculated damping The sensor calculates a suitable integration time automatically. Additional adjustments Additional settings - PIN In this menu item, the PIN is permanently activated/deactivated.
